Antimony 8-hydroxyquinolinates
Australian Journal of Chemistry, 1968Precipitation from homogeneous solution or by conventional means with 8-hydroxyquinoline in the presence of tartaric acid has been successfully employed for the determination of antimony. The complex produced corresponds to the formula SbOQ,2HQ.

Abstract The preparation of two yttrium 8-hydroxyquinolinates, one by conventional means and the other by precipitation from homogeneous solution, was investigated. Analytical data indicated that the complex prepared conventionally corresponds to Y(C9H6NO)3, and the complex prepared by precipitation from homogeneous solution corresponds to Y(C9H6NO)3·

Identification of Inhibitors against Botulinum Neurotoxins: 8-Hydroxyquinolines Hold Promise.
Mini-Reviews in Medical Chemistry, 2019Botulinum neurotoxins (BoNTs) are the most toxic category A biological warfare agent. There is no therapeutics available for BoNT intoxication yet, necessitating the development of a medical countermeasure against these neurotoxins.

Halogenation of 3-hydroxyquinoline
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19711. A study was made of the halogenation (chlorination, bromination, iodination) of 3-hydroxyquinoline. 2. The halogenation of 3-hydroxyquinoline, similar to aminomethylation, is directed to the 4 position of the quinoline ring. 3. Attempts to obtain the 2,4-bishalo compounds of 3-hydroxyquinoline proved unsuccessful.

Chloromethylation of 8-hydroxyquinoline
Analytica Chimica Acta, 1956Abstract The reaction of formaldehyde on a hydrochloric acid solution of 8-hydroxyquinoline, in the presence of hydrochloric acid gas, gave a chloromethyl derivative which is probably 7-chloromethyl-8-hydroxyquinoline hydrochloride. This compound is readily converted into the 7-hydroxymethyl derivative in alkaline solution.

Synthesis of 5-hydroxyquinolines
Tetrahedron Letters, 2010A series of 5-hydroxyquinolines has been prepared via the Skraup reaction. Several regioisomers were made either by selective displacement of a leaving group or by using a bromo substituent as a blocking group. The bromo group was found to be an excellent blocking group due to its stability during the Skraup reaction and easy removal thereafter ...

Spectrochimica Acta Part A: Molecular Spectroscopy, 1984
Abstract This paper reports the electronic absorption spectrum of 8-hydroxyquinoline in the liquid and vapour states in the region 50 000-28 000 cm −1 and the i.r. absorption spectrum in the region 400–4000 cm −1 in KBr and in the neat liquid.

Tumor-targeted delivery of 8-hydroxyquinoline
International Journal of Radiation Oncology*Biology*Physics, 1991RIF-1 mouse tumors express high levels of beta-glucuronidase activity relative to most normal tissues. The high activity can be exploited for targeting specific drugs preferentially to tumor tissues. In this study we examined the kinetics of 8-hydroxyquinoline (8-OHQ) accumulation in tumor and in several normal tissues resulting from the in vivo ...

[Oral provocation of a hydroxyquinoline eczema. Hematogenic contact eczema from hydroxyquinoline].
Dermatosen in Beruf und Umwelt. Occupation and environment, 1983We inform about an eczema reaction from inside after perception of Reasec Plus. This hydroxyquinolin substance caused a generalized dermatitis at a patient who is contact sensibilized against Vioform. The sensitivity index found out among our patients is very little (0,85%).
